ok i am going to add all three drivers that have worked for other members in to one post here as this is becoming a very long topic with drivers listed all the way through it.
Catsmaty's driver, can be found here.
to install that driver please follow catsmaty's advise.
Thank you, just emailed them to you on firstname.lastname@example.org, here is the step by step guide on how to use them:
I read allot about the problem with the Blue RS232 USB to Serial cable problems bought from fleebay, I bought one marked HL-340 and I followed the great post but none of the drivers worked for me till I got sick and I was about to through it in the bin till I found the solution, please follow these steps to solve your issues:
1- Download the winzip ebayhl-340 file on to your desktop and make sure that your cable is unplugged.
2- Make a new folder on your desktop
3- Unpack the winzip file in to your new folder
4- Burn a CD with the three folders found inside your new folder
5- Open the folder called HL-232-0108 and run the Setup For HugePine, if you get any messages press continue anyway.
6- Open the second folder called HL-232-340 and install the HL-340 and if you get any messages press continue anyway.
7- Open the folder called HL-232-2303 and then HL-2303, and run the HL-2303 setup, if you get a message saying to remove or reinstall, click on reinstall.
8- Reboot and then plug the cable, windows will recognize it as HugePine USB to serial and will ask you for the drivers, let windows install the driver automatically, again if you get any messages press continue anyway, once done it's ready to use.
you need to make sure everytime to use only the same USB port to avoid repeating these steps.
bobidiboo driver is the usb-serial zip on the bottom of this post
A driver i found for woodworker which is a different cable ch341ser/hl340 is the ch34rser zip at the bottom of this post.
if one of these drivers don't work for you please remember to uninstall it before you move on to the next or you will end up with a driver tossed salad in your system 32 folder then none of the drivers will work for you.
found another possible driver for another member today for the HL-340 cable.
this one is made by proflic and named PL-2303 I have added the driver to the board. pl2303.zip
